In our experience, we have found that DDS is one of the few companies that are able to combine the skills of roofing and waterproofing with craftsmanship and good quality finish painting to produce results that are both functional and attractive in appearance.We have recommended DDS as a contractor to install our products countless times and have introduced DDS to clients who have had unfortunate experiences with other contractors who have failed to install our products correctly; DDS was able to successfully salvage and make good on these jobs....among the hundreds of professional contractors with whom we deal, DDS is one of the best!
